A short link 9 conto enter the space between the grip-sections, nects the bell-crank to a bracket 10, attached as clearly shown in Fig. 1.

This Fig. 1) of the box 2 to guide the rod in its frame travels within the slot 18. At the lower vertical movements. The lower end of this rod is formed with an arm 43, provided with a pulley 44, and said arm is designed to contact with cam-blocks 45 and 46, arranged within the conduit adjacent to crossings, as will be further explained.

The shifting-rod 39 is provided with a spring-dog47, adapted to contact with a'springpressed bell-crank lever 48, to which is loosely connected a locking-arm 49, which enters an opening 50 in the head of the wedge-bar 33 to lock said bar, except during the operation of the shifting-rod 39.

.51 indicates a rigid arm secured to the bottom of the conduit at one side of the crosscable. This arm, to effect the revolution of the grip, strikes one of the pins 52, projecting from one of the sections of the grip, as clearly seen in Figs. 1 and 2. A spring 53 should be arranged on each side of the grip secured at their rear ends to any convenient part of the frame 15 and having their free ends in contact with the grip-sections and provided with pulleys, so that when the wedge-bar is withdrawn at a crossing these springs will force the grip-sections apart at their lower ends to release the cable. For convenience of illustration and to prevent obscuring other parts,

we have shown only one spring 53 in Fig. l and i .and rigid arm within the conduit, of a revoluble grip provided with pins to strike said omitted both springs in Fig. 2.

The block 56, secured within the conduit in advance of the cam-block 45, is adapted to be struck by the spring-dog 31 to release the notched wheel 28 and permit it to revolve one-quarter revolution when one of the pins 52 contacts with the arm 51.

Having described the construction of our improved device, we will now proceed to explain its mode of operation: Itwill be understood that the mechanism hereinbefore described, except the shifting-rod and parts controlled thereby, is to be under the control of the gripman, the raising and lowering of the box 2 carrying the wedge-bar operating to control the grip. WVhen a crossingis reached, the arm 43 of the shifting-rod 39 strikes the cam-block 45 and draws said rod downwardly. The dog 47 contacts with the bell-crank lever 48, thus withdrawing the locking-arm 49 of the wedge-bar, and at the same movement the spring 38 of the lever 37 is depressed and the continued movement of the shifting-bar draws down the lever 37, thus raising the wedge-bar and releasing the grip. As soon as the arm 43 passes the cam-block 45 the dog 31 strikes the block 56 and releases the notched wheel 28. The continued forward movement of the car will cause the arm 51 to strike the nearest pin 52 of the grip, thus causing the latter to revolve one-quarter revolution and jump the cross-cable 58, after which the arm 43 of the shifting-rod strikes the upwardlyinclined cam-block 46, thus again raising the shiftingrod, lowering the wedge bar, and causing the other elements of the mechanism to resume their normal positions.

It will be apparent that many slight changes or variations in the details of construction of our imporved device may be resorted to without departing from the spirit of our invention, and hence we desire it to be understood that we do not limit ourselves to the exact construction shown in the drawings, but reserve to ourselves the right to make all such modifications as may properly fall within the scope of our invention, as specified in the following claims.

Havin g fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the truck, of a sliding box supported thereby, a verticallymovable wedge-bar, a revoluble grip provided with projecting pins, an arm to strike said pins, a shifting-rod, and cam-blocks arranged within the conduit to contact with said shifting-rod, substantially as described.

2. The combination, with the contact-blocks arm, a shifting-rod to engage said blocks, a

wedge-bar, and locking mechanism between the wedge-bar and shifting-rod, whereby the wedge-bar is raised as the shifting-rodis lowered, and vice versa, substantially as described.

33. The combination, with the two-part revolving grip provided with projecting pins, of the rigid arm adapted to strike said pins, and pulleys or rollers arranged upon the grip-sections oppositely in pairs to support the cable, substantially as described.

4. The combination, with the truck and sliding box, of a movable wedge-bar arranged in said box, a sliding shifting-rod arranged in said box, locking devices between the wedgebar and shifting-rod,a frame depending from the truck and supporting a revoluble grip, and means, substantially as described,forautomatically revolving said grip a partial revolution at cable-crossings, substantially as described.

In testimony whereof weafiix our signatures in presence of two witnesses.
